Short Overview of the pattern

The hat is knitted in-the-round from the bottom edge up in 2-color brioche stitch. The hat begins with rounds of regular brioche stitch, which is worked for 2" (5 cm). Then the body of the hat is worked in a combination of regular brioche and brioche lattice, which is achieved by working br3-3 (brioche gathered 3 into 3 st). The top of the hat is shaped with brioche decreases.
